"Above the Earth-rank Alchemist, there is indeed a Heaven-rank Alchemist. If I'm not mistaken, the Human Alchemist is capable of refining pills for ordinary cultivators, while the Earth Alchemist can refine pills for Immortals. I wonder what's so special about the Heaven Alchemist?" Han Li nodded thoughtfully, then asked.

"The distinction between Human and Earth Alchemists is similar to what you described. As for Heaven Alchemists, also known as Dao Alchemists, they hold the highest status in the Immortal World. The sole criterion is whether they can refine Dao Pills," Mo Guang said slowly.

"I don't know what Dao Pills are, and how they differ from other pills?" Han Li was taken aback and asked.

"Dao Pills are pills that contain the power of the laws of heaven and earth," Mo Guang replied.

"Containing the power of laws… Could it be that after taking this pill, one can directly comprehend the power of laws?" Han Li's heart stirred, as if he had thought of something.

"In the Immortal World, those who transcend tribulation and become Immortals mainly master the power of laws through two paths. One is through cultivating various cultivation methods and scriptures, constantly comprehending them in the long course of cultivation, and eventually, they may have a chance to comprehend the power of laws… The second is to refine spiritual materials containing a certain power of the laws of heaven and earth into Dao Pills and take them to comprehend," Mo Guang continued expressionlessly.

"Dao Pills actually have such an effect? Wouldn't that save tens of thousands, or even hundreds of thousands of years of arduous cultivation and comprehension?" A stormy sea had already risen in Han Li's heart, but after taking a deep breath, he said with a normal expression.

"Not so. Even if one is lucky enough to obtain a Dao Pill, there is only a very low probability of comprehending the relevant power of laws. However, even so, it will be of great benefit to comprehending the relevant laws in the future," Mo Guang shook his head and said.

"This probability of comprehending the power of laws should be related to the grade of the Dao Pill," Han Li said after pondering for a moment.

"That's natural. Generally speaking, Dao Pills must contain the power of laws, but pills containing the power of laws are not necessarily Dao Pills. The specific criterion is to see whether Dao patterns can appear on the surface of the pill after the pill is successfully refined, and the grade of the Dao Pill is judged based on the number of Dao patterns," Mo Guang explained eloquently.

"Dao patterns… Then do you know how many Dao patterns the highest grade Dao Pill will have?" Han Li silently noted it in his heart and continued to ask.

"At most, there are nine Dao patterns, which is a Nine-Grade Dao Pill, which is almost a legendary existence. Even a One-Grade Dao Pill is a spiritual object that seizes the creation of heaven and earth, and it is also extremely precious and rare in the Immortal World," Mo Guang said.

"I see… No wonder Heaven Alchemists have such a high status in the Immortal World," Han Li nodded.

"I know that Fellow Daoist Han was an accomplished alchemist in the Spirit World. Asking about this today probably means you have some thoughts about this Heaven Alchemist as well. However, as far as I know, one Earth Alchemist may eventually appear among a thousand Human Alchemists, and even among ten thousand Earth Alchemists, one may not be able to become a Dao Alchemist. As for Heaven Alchemists who refine high-grade Dao Pills, there are even fewer," Mo Guang said meaningfully.

"Haha, alchemy requires experience. The spiritual materials of heaven and earth containing the power of laws are inherently rare, so where are there so many materials to practice with?" Han Li smiled faintly, not at all surprised.

"What you said is indeed one reason. Another reason is that the Dao Pill recipes are equally rare and basically all controlled by the major forces in the Immortal World. The Heaven Alchemists in the Immortal World are like the Alchemy Grandmasters in the Spirit World, mostly attached to the major forces in the Immortal World. Outsiders rarely see them at all," Mo Guang said.

Han Li frowned upon hearing this.

"By the way, there is another rumor about Dao Pills. The so-called Dao Pills are naturally formed. The same Dao Pill recipe can only be comprehended by a certain number of Heaven Alchemists. Once the number is sufficient, those who come later will no longer be able to comprehend the method of refining this Dao Pill," Mo Guang added, as if he had thought of something.

"There's such a thing? Isn't that too mysterious?" Han Li was slightly stunned.

"No one has verified the truth of this rumor, but everyone would rather believe it than not. Generally, if one obtains a Dao Pill recipe, they are absolutely unwilling to spread it unless it is absolutely necessary," Mo Guang said.

Han Li smiled wryly. He quite agreed with this point, after all, he would do the same if he were in their shoes.

"That's all I know about Dao Pills and Heaven Alchemists. I hope it can help Fellow Daoist Han," Mo Guang said lightly, his figure swaying as he was about to disappear into the shadows.

"Thank you, Fellow Daoist Mo Guang. Wait a moment, I have one more thing to ask," Han Li suddenly remembered something and stopped Mo Guang.

"Oh, what else does Fellow Daoist Han need?" Mo Guang said.

"It's about the Immortal Essence Stone. I would like to ask Fellow Daoist to introduce it to me," Han Li said.

"Oh, the Immortal Essence Stone is a good thing. It can quickly replenish the Immortal Spiritual Power in the body during battle, and it can also be used to increase the speed of cultivation. It is a scarce item no matter where you go," Mo Guang said.

"No wonder it can be used as currency. I wonder, does it take a long time to condense an Immortal Essence Stone?" Han Li asked.

"It varies from person to person. Generally speaking, a late-stage True Immortal can condense one in a year, a mid-stage True Immortal needs ten years, and an early-stage True Immortal needs more than a hundred years," Mo Guang said after a moment of pondering.

"A hundred years…" Han Li frowned.

The teleportation array costs five Immortal Essence Stones. He originally planned that if it didn't take long to condense an Immortal Essence Stone, he could work hard to condense it himself. Now it seems that this path is not feasible.

"The Immortal Essence Stone I just mentioned refers only to the low-grade Immortal Essence Stone. Like Spirit Stones, Immortal Essence Stones are also divided into four grades: low-grade, mid-grade, high-grade, and top-grade. Generally speaking, only high-level Immortals can condense high-quality Immortal Essence Stones," Mo Guang continued.

"Then, besides needing to constantly inject Immortal Spiritual Power, are there any other restrictions?" Han Li said.

"During the condensation of Immortal Essence Stones, cultivators cannot cultivate. Therefore, unless forced to, no Immortal is willing to do such a thing that harms themselves and benefits others. So in the Immortal World, the number of Immortal Essence Stones of any grade is very small and extremely precious," Mo Guang said.

Han Li nodded slowly, but smiled bitterly in his heart.

In that case, his hope of exchanging for Immortal Essence Stones is probably not great.

Seeing Han Li pondering in silence, Mo Guang didn't say anything more. His figure flickered and merged into Han Li's shadow, disappearing without a trace.

…

Deep into the night, the bright moon hangs in the sky.

Above the summit of Youyang Mountain, a ray of escaping light suddenly burst forth, like lightning, and disappeared in a flash.

Not long after, in a remote sea area tens of thousands of miles away, a figure emerged from it and floated on the surface of the sea.

This person was dressed in a green robe, tall and sturdy, and it was none other than Han Li.

He saw that his eyes were as bright as stars. He reached out and grabbed in front of his chest, throwing it towards the sky. Then, his lips parted slightly and he silently chanted.

As bursts of chanting sounded, the small bottle suspended in the sky began to vibrate violently, and the heaven and earth vitality within the surrounding sea area also began to become a little restless.

A hazy green spherical light curtain began to expand little by little, enveloping in all directions, and the waves on the surface of the sea were also surging secretly…

In the blink of an eye, seven days and seven nights had passed.

As a small crystal grain and the small bottle, which had become almost transparent, slowly fell from the sky, the surface of the sea completely returned to a calm and peaceful appearance.

Because he had taken a Return Origin Pill in advance, he was not sucked into a bag of bones as he had been in the previous few times, but at this moment his expression was still quite listless. After raising his hand to take the two treasures, he immediately flipped his hand and took out a emerald green jade bottle, pouring out a Gaze Origin Pill and sending it into his mouth.

He first felt a burst of coolness in his throat, but as the pill slowly entered his abdomen, this coolness quickly turned into a warm current, which began to flow in his limbs and bones, eventually converging into his dantian.

The dantian only felt slightly hot, and then he felt that the speed of absorbing the heaven and earth spiritual energy suddenly increased, and a steady stream of spiritual power entered the dantian, and then transformed into strands of extremely pure Immortal Spiritual Power.

Previously, when he heard the Shopkeeper Lu say how unique high-level pills were, he did not feel much. After taking it this time, he realized that it was really different from the pills he had taken before.

After all, a pill that can greatly increase the speed of a True Immortal cultivator's recovery of Immortal Spiritual Power in a short period of time can be used to increase the speed of condensing Immortal Essence Stones if taken during the condensation of Immortal Essence Stones. Its preciousness can be imagined.

After resting in place for a while, Han Li's body was filled with escaping light, and he shot towards Blackwind City.

When Han Li's figure appeared again in the hall of Thousand Elixir Hall, Shopkeeper Lu, who was greeting a regular customer, saw him at a glance. He was first a little surprised, but soon informed the regular customer and greeted him with a smile on his face.

"Senior has graced us with your presence, a great loss of welcome, a great loss of welcome…" He said with a smile while cupping his hands in salute.

"I bought some pills from the shopkeeper earlier, and the effect was really good after taking them, so I thought I'd come and take a look again," Han Li said with a slight smile.

"Senior is welcome to our elixir hall at any time. Senior, please follow me." The smile on Shopkeeper Lu's face grew even brighter, and he hurriedly led Han Li upstairs again.

The situation was similar to the previous few days. The fifth floor was still very quiet, with no customers except for a few servants.

"I wonder if Senior wants to buy some more Gaze Origin Pills, or try some other pills?" Shopkeeper Lu asked after arriving on the fifth floor.

"Not in a hurry. I have some questions I would like to ask first, and then I will see which pill to buy," Han Li said calmly.

"Senior, please ask." Shopkeeper Lu was slightly stunned, then nodded.

"The pills in your hall are not only extremely fast to dissolve, but also have extraordinary efficacy. I believe this is closely related to the quality of the spiritual medicine used and the alchemist's alchemy skills," Han Li asked.

"That's true. It seems that Senior is also an expert in the art of pills," Shopkeeper Lu said with a smile.

"I can't be called an expert, but I have fiddled with some alchemy techniques before," Han Li waved his hand and said.

"May I ask Senior, what level of alchemist are you?" Shopkeeper Lu seemed a little surprised when he heard this, and hurriedly asked.

"To be honest, I have always been in a remote place, building a cart behind closed doors. I have never compared myself with alchemists from the outside world. Since I happened to be here today, I would like to ask your hall to send an alchemist to examine me, so that I can figure out my true alchemy level," Han Li said with a look of embarrassment upon hearing this.
